'Ihis invention relates to improvements in a transfer apparatus adaptedmore particularly to apply transfers to relatively small sized objectsof manufacture that may be readily brought into cooperative relationwith the apparatus, such as, for instance, articles of clothing or thelike.

The main object of this invention is to provide a simply constructed andoperated apparatus that will rapidly and eilicaciously apply transfersto relatively small objects such as hosiery or otherarticles ofclothing.

In carrying out the above mentioned object, I preferably utilize atransfer tape comprising a relatively long base strip composed of paperor other suitable material having required markings or impressionsduplicated thereon at spaced intervals. Thse transfer markings orimpres'- sions are composed of vink or other composition which may bereadily melted when subjected to a relatively high temperature of heatand these markings may be applied to the base by printing methods in theordinary manner. The transl fer tape is Vprovided in long strips formedin rolls. In my novel transfer machine the tape is automatically fedintermittently from the roll over articles to which `the transfer is tobe applied, between a platen for supporting the articles and a heatingelement, and the heating element is brought into pressure engagementwith the transfer base and article, whereby the ink is melted andtransferred from the paper base to the article, and the transfer markingor impression is thus imprinted on the article.

It is a well known fact that paper is highly susceptible to variationsin moisture content of the surrounding atmosphere with the result thatthe distance between the successive transfer.

markings or impressions varies with each change of` the moisture contentin the air, due to the contraction or expansion of the paper baseproduced thereby. This variation in the distance between the transfermarkings is` such that,- insofar as the applicant is aware, itheretofore has been very difficult to maintain the markings orimpressions in proper relation with the transfer elements of themachine.

Another important object of this invention resides in providing atransfer apparatus which will automatically bring. each successivetransfer marking or impression to a predetermined position at eachintermittent movement of the transier tape or base, irrespective of thesize of the markings, the distance they are spaced apart,

or any irregularities occurring in the spacings thereof.

A more specific object of the invention is to provide a: mechanismwherein the operation of certain elements thereof may be readilycontrolled to conform the machine to varying working conditions such asthe time required to make the transfer, the thickness of the article tobe labeled etc.

Other objects and advantages pertaining to the structure of the deviceand to the form and relation of the parts thereof, will more. fullyappear from the `following description taken in connection with theaccompanying drawings in which:

Figure 13 is a longitudinal sectional view of a 45v time switch,particularly adapted to be used in connectionl with -my transferapparatus.

Figure 14 illustrates a section of a transfer tape, particularly adaptedto be used on the ma- A chine disclosed herein.

The device as illustrated in the drawings comprises a lower base i, andan upper base or frame 2, mounted in any suitable manner upon the lowerbase l. The upper base 2 is provided at one side of the rear end thereofwith an upwardly projecting lug or arm 3 which carries a supportingshaft or stud d, as illustrated more particularly in Figures 1 and 10.'Ihe supporting shaft d has mounted thereon a pair of axially spacedbearing members 5 and'. Upon the bearings 5 and 6 is mounted a rock armI which is mounted adjacent one end thereof upon said bearings andextends outwardly therefrom over the base 2 for movement toward and fromsaid base.

'I'he arm 'I is moved about the shaft il as a pivot by motor meanswhich, in this instance, comprises a solenoid 8, mounted in the upperbase 2 at the forward end thereof, as shown in Figure 1. The plunger 9of the solenoid 8 is provided with a rack I which is in meshingengagement with a pinion II, secured to or made integral Witha crankshaft I-2 which is journaled in suitable bearings I3, which in turn aremounted in standards It, secured to the bottom 2' of the base 2,adjacent opposite sides of the pinion Il. The rack I0 is maintained inmeshing engagement with the pinion II by a'guide roller I0' journaled ona' shaft I0, secured in the upper ends of the standards It as shown inFigure 3.

One end of the crank shaft I2 has mounted thereon a crank I5 which ispivotally connected as by the pin I6 to one end ofa connecting link I'I.The link II extends upwardly from the pin vIE5 and has the upper endthereof pivotally connected to the rock arm 'I intermediate the forwardend thereof and the shaft l by means of a stud I 8 secured to said armand an eccentric collar I9 which is rotatably secured to said stud by aset screw 20, so that the distance between theaxis of the stud I6 andthe pin I6 may be varied to alter the travel of the arm Il for bringingthe heating element carried by said arm into proper relation with aplaten for a reason which will hereinafter more fully appear.

A table 22 is mounted on the upper face of the base 2 at the forward endthereof.' The table 22 in this instance is a rectangular member in planView and is secured to the base by four yclamping screws 23. In orderthat the table may be adjusted relatively to the base 2,1 have providedthe same with four spacing screws 26 positioned in close proximity to arespective clamping screw as shown in Figures 1 and 2. The lower ends ofthe screws 24 are adapted to engage the adjacent portion of the base 2so that by loosening the clamping lscrews 23 the height of the table 22may be varied by the manipulation of the spacing screws 24 and then thetable may be secured to the base in the adjusted position by the screws23.

The table 22, in this instance, is provided with a central recess 22 inlongitudinal alignment with the outer end portion of the supportingshaft 4 for the rock' arm 'I. In the recess 22 is positioned a platen 26to be supported by the table. The platen 26 is preferably composed ofvulcanized rubber or other slightly resilient material, and has theupper surface thereof positioned a relatively short distance above thetable 22 yfor supportably receiving thereon the article, such ashosiery, to which the transfer is to be applied.

, The table 22 as shown more particularly in l Figures 1 and 11 may beprovided with a pair platen 26 to assist the operator in properlypositioning the article upon which the transfer is to be applied uponthe platen 26.

It willnow be observed by referring to Figure 2 that the rock arm Iextends outwardly from the arm 3 of the base over the table 22 in avertical plane at one side of the platen 26 and that the rear or pivotedend of the arm is provided with an integral extension or hub 'I' whichrey lar in plan view and has secured to the bottoml face thereof in xedspaced relation thereto a heating'element 35.

The element 35 may be constructed in any suitable manner and ispreferably provided lwith a heating coil, not shown, adapted to receivean electric current therethrough. The element 35 in this instance issecured to the carrier plate 34 by four screws 36 and spacing members 3land 38. The spaced members 38 are, as shown in Figure 9, tubularmembers, while the spacing member 31 is in the form of a rectangularstrip which extends across the inner 0r rear side of the element andplate. The spaced members 3l and 38 are preferably composed ofinsulating material so as to prevent as much heat as possible from beingtransmitted from the heating element to the carrier plate 3and arm l.

The carrier plate 3d also has a guide plate 40 mounted thereon forguiding the transfer base or tape over the carrier plate 36 and aboutthe heating element 35. This guide plate lil is vpreferably composed ofthin spring metal and is secured to the rear or inner side of the plate36 by screws 4I. The plate extends upwardly from the screws 4I as shownin Figure 1 and across the upper face of the carrier plate 34 inslightly spaced ,parallel relation thereto and has the outer end portiond2 thereof bent to extend downwardly in spaced parallel relation with.the outer or forward side faces of the plate 34 and heating element 35.The outer end of the portion 42 of the carrier plate may, as shown inFigure 1, be bent 'rearwardly at substantially right angles to theremaining portion thereof and is normally positioned a relatively shortdistance below the plane of the lower face of the heating element fornormally maintaining the transfer tape in spaced relation to the lowerface of the heating element.

It will now be observed by referring to Figures 1 and 2 that the hub Iof the arm l forms a convenient support for the roll of transfer tapeand is utilized for this purpose as indicatedrby broken lines in thesefigures. The tape is threaded from the roll as R, across the upperportion of the guide plate 40 and thence downwardly across the outerface of the portion 42 of the guide plate and thence rearwardly aboutthe ,end portion 42 thereof, across thelower face of the 'heatingelement 35 and then be` tween a drive roll 44 and a pressure roll 45,

adapted to intermittently draw the transfer tape from the roll R overthe guide plate 40 and across the lower face of the heating element 35.It will, therefore, be understood that the tension produced upon thetransfer tape by the action of the feed roll 44, in drawing the sameover the guide plate 4D, tends to deflect the end portion 42 of saidguide plate inwardly toward the heating element 35 and in order toprevent this, I have provided` the guide plate with apair of 5 lightflexible' control rods 46 which have their outer ends secured to theportion 42 of the plate bythe extension thereof beneath inwardly stampedears 42'. formed on the plate 42.

The rods extend inwardly from the connection with plate 40 between theheating element 35 and the carrier plate 34 in a plane just inside ofthe spacing members 38 and have their rear ends secured in the spacingstrip 31 as illustrated in Figure 9. These control rods 4B l5 not onlyfunction to maintain the portion 42 of the guide plate against beingdeflected inwardly during the feeding of the transfer tape, but ,alsofunction to maintain said portion 42 of the guide plate in substantiallyparallel spaced relation with the front sides of the carrier plate 34and heating element 35 when the tape is brought into contact with theheating element by the engagement of said element with the articlepositioned on the platen 26, and thereby prevent a -variation in theregistration of thev markings or impressions carried by the tape withthe heating element, which might otherwise be caused by the inwarddeflection of the portion 42 of the guide plate, by maintaining auniform distance of travel for the transfer tape. It will also beobserved thatinasmuch as the inwardly directed end portion 42' of theguide plate 4!! is of less width than the distance be- .tween theportion 42 and the adjacent side of the heating element 35, the guideplate is free to move upwardly beyond the lower face'of said element bythe engagement of the end 42' with the platen 2Gv as the heating element35 is brought in to operative 'relation with the platen so that theportion 'of the transfer tape T, adjacent the heating element, mayfreely move into Contact with-said element and the ink definingA theemblems or impressions on the transfer tape will be melted andtransferred to the object posi- 43 tioned on the platen 26.

The hereinbefore mentioned feed roll 44 comprises a shaft 48 journaledadjacent one end thereof in suitable bearings 49 provided in the 'rockarm 1 in inwardly spaced relation to the 50 stud I8 for the drive linkl1 as shown more clearly in Figure 8. One endportion of the shaft 48extends outwardly from the arm 1 in a horizontal plane over the base 2in longitudinal alignment with the hub 1 of the arm 1 and car- E-T `rierplate 34. This extended portion of the shaft 4 8 is preferably coveredby a sleeve 44 composed of rubber or other suitable material adapted tofrictionally engage the transfer tape as it is passed between said shaftand the pres- C0 sure roll '45. The opposite end of the shaft 48 extendsa short distance .beyond the opposite side of the arm 1 and has securedthereto a worm gear 50 which is in meshing engagementv with.

a worm 5I mounted on a drive shaft 52v as shown I C5 more particularlyin- Figures '7 and 8.v

This drive `shaft 52 is journaled at opposite sides of the worm 5| insuitable bearings 53 and 54 provided in the housing 55, for the gearmembers 50 and 5I and which'is secured to lthe 7 0 outer face of the arm1 in any suitable manner. The drive shaft 52 extends rearwardly from thehousing 55 and is operatively connected in any suitable manner with anelectric motor 51 secured to a bracket 58 which in turn is secured to 75the rear-end of the arm 1 to move therewith.

The motor 51 is preferably of the series wound vtype to obtainrelatively high starting torque.

The motor51 may be energized from any suitable source of potential andin a manner which will hereinafter be more fully explained, and when 5the circuit for the' motor 51 is broken it is desirable that theoperation of the motor and-the feed roll 44 driven thereby, bediscontinued immediately and for this purpose I have provided a simplebrake mechanism 59 which comprises 10 in providing one of the bearingmembers as 54 for the shaft 52 with an outwardly projecting annularflange 54' and the shaft 52 with a metallic disc 60 keyed thereto so asto be rotated thereby but free to be moved axially thereon. A pair 15 ofdiscs 6I composed of fiber or othersuitable material is rotatablymounted on a shaft 52, one at either side of the disc 60 for frictionalengagement with said latter .disc and with the flange vportion 54' ofthe bearing 54. '20

These brakediscs 60 and 6| are brought into frictional engagement witheach other and with the bearing flange 54 by means of .a brake lever 62which, in this instance, has the upper end thereof forked and fulcrumedas at 63 to a 25 bracket 64 secured to the adjacent portion of thearm 1. The upper forked portion of the lever -62 is curved forwardlyfrom the fulcrum 63 as at 62 for engagement with the rearmost disc/6| ofthe brake at opposite sides of the shaft 52. 30 The lever 62 extendsdownwardly from the curved portion 62 and has secured to the lowerendthereof a tension spring 65 which, in turn, is connected with thehousing 55, said spring being tensioned -to normally swing the levertoward 35 the brake discs to maintain said discs in frictional contactwith each other,

Any suitable means may be provided for relieving the braking action ofthe discs 60 and 6| upon the shaft 52 to permit the free rotation of 0said shaft and for this purpose I have shown a. solenoid 68 secured inany suitable manner to the arm 1 at the rear of the brake lever 62. Theplunger 69 ofthe solenoid is extended through an elongated slot providedin the brake lever 62 5 intermediate the ends thereof and the outer endof said plunger is provided with apin 1D which extends outwardly-beyondsaid plunger across the adjacent-portion of the lever transversally ofthe slot. It will .thus be understoodthat when 50 the solenoid 68 isenergized to draw the plunger 69 inwardly that a rearward swingingmovement of the brake lever 62 will be produced thereby against theaction of the spring 65 so that the curved portion B2 will be movedrearwardly out u of contact with the brake disc 6|.

QThe hereinbefore mentioned pressure roll 45 as shown more particularlyin Figures 1 and 8 comprises a central shaft or core 12 encased in asleeve 13 composed of any suitable material 60 adapted to cooperate withthe feed"roll sleeve 44 to effect intermittent movement of the transfertape. The ends ofthe core 12 of the pressure roll are rotatablyconnected as at 14 with the ends of a bifurcated rock arm 15, journaledon the .'55

' the reception of the shaft 80. Each rod 19 exmally engages the tape Tas said tape passes over Y tends through the block 82 at one side of theshaft opening and has the outer end portion thereof return bent andextended into a slot 82' provided in the under side of the block incommunication with the shaft opening whereby said end of the rod 19 mayfrictionally engage the shaft 80.

I also employ tension means such as the spring `strap 89 for releasablymaintaining the transfer roll R from rotating'upon the support 1'. Thisstrap 89 is an elongated member as shown in Figures 1 and 2, having oneend thereof pivotally mounted upon the shaft 80 intermediate the blocks82. lThe strap 89 extends outwardly from the shaft 80 over the roll Rand has the outer or fre-e end thereof extended downwardly forfrictionally contacting with the peripheral surface of the roll R.

As before stated, the tape T is drawn from the roll Rover the guideplate i0 and in so doing is passed beneath a, guideroller 86 which ismounted in any suitable manner upon the arm l' interlmediate the ends ofthe arm and in theplane of the upper face of the guide plate 90.

Interposed between the guide roller 86 and the guide plate 90 is aswitch member 90 adapted to be actuated by the ink on the transfer tapeconstituting the, emblem or transfer marking, for controlling theoperation of the motor 51 and the feed roll driven thereby in a mannerpresently described.

This switch 90, as sh'own more clearly in Figures 1, 2; 5 and 6,comprises a supporting arm 92 which has one side thereof provided withan inwardlyA extending recess 93 adjacent one end thereof, adapted toreceive therein the arm 1 as illustrated in Figure 5. The arm 92 isclamped to the arm l by means of a screw 94 to maintain the switch armin fixed relation with the rock arm 1 and at the same time permit theadjustment of the switch arm relatively to said rock arm. The switch arm92 extends outwardly fromthe arm 1 in a plane in longitudinal alignmentwith.' the hub 1 and carrier plate 34, and has secured thereto asupporting plate 95. The plate 95 is arranged in parallel spacedrelation with the lower face of the arm 92 "for the reception of switchcontrol member 96 therebetween.

This switch control member comprises an elongated substantially at bodyportion 91 of substantially the same length as the supporting plate 95and preferably equal to or greater than the width of the transfer tapeT. The rear side of the body portion 91`o the control member 96 isprovided with a pair of vertically disposed ears 98` which are pivotallyconnected as at 99 to a pin secured to the switch arm 92 as illustratedin Figure 6. The central portion of the body 91 is provided with adownwardly extending substantially flat, channel portion 91 arranged inthe plane of the supporting plate 95, which nor- 1 the plate 95. The'side of the body portion 91 the fixed terminal with the platen 26 andheating element 35 by opposite the ears 98 is provided with an upwardlyextending substantially V shaped projection i0| arranged adjacent theinner side of the arm 92 in close proximity to the fulcrum pin |00 andadapted to engage a movable contact arm 902 of the switch 90 which ispivotally mounted at one end upon the pin |00. The arm |02 extendsforwardly from said pin over the projection |0| and has the outer orfree end thereof provided with a contact element adapted to engage acorresponding contact element on a xed terminal |03 secured to the arm92 in insulated relation therewith.

The contact arm |02 and control member 98 are yieldingly maintained inthe lowermost position by a spring |05 secured at one end to the arm 92and having the outer portion thereof engaging the upper face of the arm|02 as shown in Figure 5. The structure of the contact arm |02, xedterminal |09, and the control member 96 are so related to each otherandto the tape T that when a portion of the tape intermediate adjacentemblems or impressions is present between the channel member 91' and thesupporting plate 95 the electric circuit passing through the switch willbe closed and when a portion of the tape having an emblem or impressionis present between the channel portion 91' and the plate 95, thethickness of the ink forming the emblem or. impression will besuflicient to rock the control arm |02 upwardly out ofengagement withthe terminal |03 and open the circuit.

Mounted in the circuit ,for the motor 51 and adapted to be controlled bythe action of the switch 90 is a relay switch mechanism i l0. As shownmore clearly in Figures 3 and 4 this relay switch is mounted in theforward portion of the base 2 opposite the solenoid 8 and comprises aspring contact arm lll which is secured at one end in insulated spacedrelation to a supporting block ||2 which, in turn, is secured in anysuitable manner, as by screws H3, to a partition H9 provided in the base2 adjacent the forward end thereof. The outer or free end of the contactarm is adapted to engagea fixed terminal H6, secured in insulated spacedrelation to an adjacent portion of the base 2, such as the partition H9.The contact arm l is tensioned to normally remain' in engagement with H6for maintaining the switch closed.

The contact arm l is manipulated to effect the opening and closing ofthe switch by means of a spring H8, a solenoid ||9 and a link |20, saidlink being connected at one end, as at |2|, to the outer end of theplunger V22 ofthe solenoid ||9. The spring 8 is in this instance, a

the plunger |22 at the rear of the pivot |2| for vthe link |20. Thespring I |8 is tensioned to normally urge the solenoid plunger |22outwardly toward the contact arm `The link has the outer end portionthereof provided with an aperture adapted to receive the contact armtherethrough. The contact arm is provided with a cam block securedthereto in operative alignment with the plunger |22. This cam blockV |25has the outer or rear face thereof formed with a stepped portion |25adapted to be engaged by the rear wall of the aperture in the link |20,when said link and the plunger |22 are moved outwardly toward thecontact arm by the spring |I8. The solenoid ||9 may be secured in anysuitable manner to the adjacent portion of the base 2 in operativerelation with the contactA arm The operation of the relay switchmechanism ||0 is as follows: The contact arm I is normally maintained inits outermost position in spaced relation to the terminal ||6 by theaction of the spring ||8 upon the plunger |22 and link |20. When thecontact arm is in the open position as illustrated in the Figure 4, thelink |23 is in a slightly downwardly inclined position in engagementwith the stepped portion |25' of the block |25 with the outer endthereof in the path ofmcvement of a trip arm |26 secured to the 4drivelink I1.

I'he relation of the trip arm |26 to the link |2|0 is such that as thelink |1 is moved from the lowermost position to the uppermost positionfor producing an upward rocking movement of the rock arm 1, the trip armwill engage the outer end of the link |20, as said arm is moved upwardlyin the path indicated by the dot and dash line X, Figure 4, and movesaid link beyond the stepped portion |25 of the block |25 and therebyrelease the contact arm and permit said arm to move into engagement withthe terminal I|6 for closing the switch. v

After the trip arm |26 has moved beyond the link |20 out of engagementtherewith, said link will rest upon the upper end of the stepped portion|25v and when the switch is to be again opened the solenoid ||9 isenergized to eiect the inward movement of the plunger |22 against theaction of the spring ||8. As the plunger |22 is thus moved inwardly orin a direction away from the contact arm lll, the link |20 will be drawnawa-y from the contact arm until the inner wall of the aperture of thelink passes beyond the upper end of the stepped portion |25 whereuponthe link will freely swing downwardly about the pivot 2| until it comesinto engagement with the lower end of the stepped portion |25. Then asthe solenoid ||9 is de-energized, the spring I8 will move the plunger|22 and link |20 outwardly and thereby swing the contact arm in acorresponding direction out of contact with the terminal H6.

In operation, the rock arm 1 is normally maintained in its uppermostposition by a spring |30 secured at one end to the armas by a lever |3|and at the other end to the base 2 as by a lever |32; see Figure 1. Whenthe arm 1 is in its uppermost position' the link |1and crank arm I5 willbe in their extended position in a straight line passing through theaxis of the stud I8 and shaft I2 'and thereby limit the upward movementof the arm 1. Furthermore when the arm 1 is in the uppermost position,the plunger 9 of the solenoid 8 will be maintained in its outermostposition by the action of the pinion upon the rack |0 as illustrated inFigure 1. The transfer tape is threaded from the roll R beneath theguide roll 86 and between the switch control member 96 and plate 95, andthence over and around the guide plate 40 beneath the heating element 35and then between the drive roll 44 and pressure roll 45 as indicated bybroken lines in Figln'e 1. The tape is arranged with the side thereofupon which the emblem is placed, facing outwardly and the tape isarranged with one of the emblem portions thereof, as T', Figure 14 inpredetermined registration with the lower face of the heating element 35and the switch 9.0 is adjusted along the arm 1 to bring the portion 91of theswitch control member 96 into contact with the forward end portionof a transfer emblem so that the switch will be maintained in the openposition.

The switch 90 is electrically connected with the solenoid ||9 by acircuit |38 which has incorporated therein the secondary coil of atransformer |39 which has the primary coil thereof connected with themain supply circuit |36 by a circuit |40 as shown in Figure 12. Themotor 51 is supplied with current from the -circuit |36 which hasincorporated therein the relay switch ||0 and also the brake solenoid 68which is arranged in series with the relay switch. Current is suppliedto the operating solenoid 8 by a circuit |42 connected with the circuit|36 and which has therein a manually controlled switch |43 by which theactionof the solenoid may be governed.

Heat is supplied to the heating element 35 through a circuit as |35connected with a main supply circuit |36 (see Figure 12) adapted to beconnected with any suitable source of potential not shown. Thetemperature of the heating element 35 vmay be controlled by a rheostatswitch |31 provided in the circuit |35.

Operation Assuming now that the heating element 35 is at the propertemperature and that the arm 1 and elements associated therewith are inthe normal inoperative position. When it is desired to operate themachine the operator rst places an article'such as a piece of hosiery towhich the transfer 1s to be applied upon the platen 26. The operatorthen closes the switch |43 in any suitable manner as with the foot, toclose the circuit |42 and supply electric current to the solenoid 8. Asthe solenoid 8 is thus energized the plunger 9 and rack I0 are drawninwardly producing a corresponding rocking movement 'of the crank shaftl2. This movement 'of the crank shaft is preferably slightly less thanand suflicient to draw the arm 1 downwardly against the action of theretracting 'spring |30 and bring the heating element 35 into pressureengagement with the article on the platen 26 and the transfer tapetherebetween. The switch |43 is maintained closed by the operator a fewmoments until the transfer ink has been melted by the heat produced inthe heating element and the emblem on the transfer tape thus transferredto the article. As thesolenoid 8 is de-energized by the opening of thecircuit therefor, after the switch |43 is released the spring |30 willreturn the rock arm 1.V and theheating lelement 35 together with thelink |1 and plunger 9 to the normal starting position, thereby releasingthe article receiving the transfer and permitting the same to bereplaced by another article.

As the drive link |1 is drawn downwardly by the action of the energizedsolenoid 8 the trip arm |26 will spring past the switch link |20 without4closing the contact points of the switch ||0.

However, upon the return or upward movement of the drive link |1 thetrip arm operatively engagesthe switch link |20 and permits the switchto close as the arm 1 approaches its normal uppermost position in themanner hereinbefore described. The closing of the switch I0 immediatelycloses the circuit |36 for the motor 51 and causes the operation of saidmotor to actuate the drive roll 44 and at the same time releases thebreaking action of the discs 60 and 6| by energizing the brake solenoid68.

The operation of the drive roll 44 will, of course, draw the tape fromthe roll R to bring a fresh registration with the' heating element 35.This transfer emblem or impression into cooperative movementl of thetransfer tape effects the closing of the switch 90 as, the transferemblem T in registration with the supporting plate 95 and switch controlelement 91 passes beyond these members.I 1

The closing of the switch 90 completes the circuit |38 for the solenoidI I9. As the solenoid ||9 is energized the switch link |20 is againbrought into operative relation with the contact arm ||I by the inwardmovement of the plunger |22. As the switch 90 is again opened by theengagement of the next succeeding transfer emblem with thecontrol'member 96 the solenoid ||9 will be deenergized and the switch||0 will be opened by the action of the spring I I8 upon the plunger |22and link |20 thereby opening the circuit |36 for the motor 51 and thebrake solenoid 68. The solenoid 68 thus being de-energized, permits thespring 65 to againeflect the braking action of the discs 60 and6I uponthe drive shaft 52 thereby discontinuing the drive action of the roll 44upon the transfer tape T at substantially the same time the switch`90 isopened by the engagement of a transfer emblem with the control member96.

This completes one cycle of the operation of the` machine and it isobvious that these cycles may be repeated for successively applyingtransfer markings or emblems to articles of manufacture.

It will now be observed by referring more par-v ticularly to Figure 1that the control switch 90 is positioned in close proximity to theheating element I5 so that a length of the transfer tape extendstherebetween. This has the advantage of maintaining a minimum amount ofvariation in length of the tape between the said control element and theheating element, and thus provides for substantially uniform `registration of the transfer emblems with the heating element under extremevariations in the spacing of the transfer emblems which may be caused bythe expansion or contraction of the transfer base tape as produced byvariations in the moisture content 'of the surrounding atmosphere.

Furthermore, it will be understood that owing to the operation of thefeed roll being controlled by the transfer emblem at a predeterminedposition thereof, any variation in the spacing of the emblems due to theexpansion orf contraction of the transfer tape, will effect but slightlythe relation of each successive emblem and the heating element as theyare brought into registration therewith. Also, what little variationthere may thus be produced in said relation of the transfer emblems andheating element will be maintained substantially constant and will notaccumulate by continued operation of the machine' as would be the caseif a predetermined length *f the transfer base tape was fed during eachintermittent feeding of the tape.

While a switch such as indicated at |43 in Figure 12 adapted to be fullymanually controlled may be successfully used in connection wit-h myparticularly adapted to be used in connection with my novel transfermachine.

The structure shown in this figure comprises a housing in which issecured a solenoid |5I. 'Ihe plunger |52 of the solenoid is providd withrack teeth |53 which are in meshing engagement with a-pinion |54 mountedon a shaft |55. The shaft |55 extendsdn a horizontal plane transversallyof the housing |50 and has the ends thereof Vjournaled in the sideofsaid frame in any suitable manner. A balance wheel |56 is secured tothe shaft |55 at one side of the plunger |52 and is of such weight tomaterially retard the action of the-plunger |52 when the solenoid |5I isenergized or de-energized.

In the upper portion of the housing |50 is mounted a mercury switch |51which is connected in series with the solenoid |5I. This switchcomprises a glass bulb |58 for containing the mercury and switchterminals. The glass bulb |58 is mounted in a. cradle |59 composedpreferably of rubber and which is pivotally connected intermediate itsends at |60to a bracket |6| secured in any suitable manner to thehousing |50. To one end of the cradle |51 is pivotally connected a hookmember |63 which extends downwardly in an oblique angle in substantiallyparallel relation to a pedal shaft |64 of a pedal |65. The shaft |64extends inwardly from one side of the housing |50 in an oblique planeand has the inner end thereof slideably mounted in a bearing |66.Theshaft |64 has the lower end portion thereof reduced in diameter toform a shoulder |64' adapted to be engaged by the hook member |63.

A latch |68 is pivotally mounted upon a pin |69 which extendsdiametrically through an elongated slot |10'provided in the pedal shaft|64 and has the ends thereof secured in the side wall of the housing|50. 'I'he latch |68 is an L; shaped is maintained in its normaloutermost position by a spring |14 mounted between the pedal head andthe housing |50 the hook |63 will be main. tained thereby in position tooperatively engage the shoulder |64' on. the pedal shaft. The lower endof the arm of the latch |68 extending in parallel relation with theshaft |64 is provided with a detent |68 normally positioned below thelateral projection |63 of the hook |63 and.

adapted to bemovedby the action of the laterally disposed arm of thelatch into engagement with said projection |63 for holding the hook andcradle |59 in the lowermost position when said hook is moved inwardly bythe action of the pedal v| for maintaining the cradle in the tilted`position. I

In operation the solenoid |5I is connected in one side of the circuit|42 in place of the switch |43 and when it is desired to close theswitch the operator effects the inward movement of the shaft |64 bypressing upon the pedal head |65. The downward movement of the shaft |64eiects the tilting of'the cradle |59 and the bulb |58 carried thereinabout the pivot |60 thereby causing the mercury to close the terminalscontained within y the bulb. As the pedal approaches its innermostposition the latch |66 will vengagethe hook |63 and prevent said hookfrom returning to its normal uppermost position and thereby maintainlthe cradle and the bulb in the tilted position with the switch closed.

After the switch is closed by the tilting of-the cradle thersolenoid |5|becomes energized and draws the plunger |52 inwardly against the actionof the balanced wheel |56 and a retracting spring |16 secured at oneendto the housing |50 and at the other end to the plunger |52. As theplunger |52 is thus drawn inwardly by the solenoid a trigger |11 mountedon the plunger engages the lower end of the hook-member |63 and rockssaid hook member out of engagement with the latch |58, thereby.releasing the hook and permitting the cradle |59 and bulb |58 to returnto the normal uppermost position and thereby electrically disconnect theterminals contained in the bulb. As the terminals are thus disconnectedthe solenoid |5| is de-energized and the plunger |52 again returned toits normal outermost position by the action of the spring |16. Theoutward movement of the plunger is limited by an adjustable stop |18which is secured to the housing |50 by a sc rew |19 which extendsthrough an elongated slot provided in the stop. It will thus be seenthat the position of the stop |18 determines the outward position of theplunger |52 and thereby determines the length of time it requires for thtrigger |11 to be brought into operative engagement with the hook'l63after the solenoid |5| has teen energized. y
